To all whom it may concern:

Be it known that I, GILMAN 1V. Brown, of \Yest hcwbury, in the county ofEssex and State of Massachusetts, have invented certain new and usefulImprovements in Carburetcrs, of which the following a specification.

This invention relates to a carbureter in which air forced into a bodyof hydrocarbon liquid through a floating distributor submerged below thesinface of the body of liquid, and adapted to rise and fall ,otherWords, whether the consumption of the relatively light or relativelyheavy.

The invention consists in the improve ments which 1 will now proceed todescribe and claim.

Of the accompanying dravin'gs, forming a part of thisspecific-.1tion,Figure 1 rep resents a top plan View of a carbureter embodying my invention, portions of the tank or reservoir being brokenaway, and other portions shown in section, and a portion of the float,hereinafter described, being also broken away. Fig. 2 represents asection on line 2-i2 of Fig. 1. Fig. 3 represents a section of anair-delivering inemher on line 33 of Fig. 2. Fig. 4 represents a viewsimilar to Fig. 3, showing the action under a higher air pressure. I

The same reference characters indicate the same parts in all thefigures.

In the drawings,l2 represents a tanlr adapted to contain a body oihydrocarbon liquid 13. The tank is provided with an inlot 15 fornir,ilglll an outlet 16 for the mixture of air at d l idrocarbon vaporproduced by the 'applail'htus, said mixture being hereinafter refer 'edto as gas. The air inlet 15 forms a part. of a closure 17 which isadapted to close an opel'iiug 18 in one of the walis of the tank, meanssuch as bolts 1.) being employed t0 dctuchably secure the closure 17 tothe margin of said opening. The opening 18 is of sullicicnt, size topermit the passage through it of the air distrilnltcr, float. andair-delivering conduit. hereinafter dcscrilicd. T0 the closure 17 issuitably aiiixed a casing 20, the end portions of which form bearingsfor a tubular trul'inion 21 which forms a part'ot an air conduit 22adapted to swing vertically in the tank by the turning of the trunnion21 in the casing 20. The trunnion 21 is provided with orifices 23 whichpermit the tree entrance of air froin'the inlet 15 into the trunnion 21,the latter being there fore an air-receiving trunnion formed on one endof the conduit At the opposite end upon the periphery of the deliveringtrunnion 7 24: provit ed with air-delivering orifices On the trunnion 24is mounted to rock or oscillate an air distributor comprising a central.hollow member or manifold 26 formed a box or casing, the ends of whichhave circular openings formed to receive and turn upon the periphery ofthe delivering trunnion The air distributer also comprises a pluralityof horizontal tubular foraminous airdistributing members Wl ich arepreferably arranged in two series projecting from JP- posite sides ofthe central member 26. Each delivering member includes a tube 2'? whichmay be of suitable construction providing a large number of relativelysina l air outlets of substantially uniform size. For example, the lube27 may be of perforated sheet metal or of woven wire, the openings inany 4:219 being small. that the tube is adapted to discharge a largenumber of fine jets or streams of air into the hydrocarbon liquid. Iprefer to provide each tube 27 with an external wrapping 28 of textilefabric, which may be arranged in two or more layers of different degreesof fineness; for example, there may be an outer layer of relativelythick ihbric, such as burlap, and an inner layer of finer fabric, suchas cheese-cloth.

This inner layer more minutely subdivides theairpassing from the tube,so that the is thoroughly distributed in passing through the outer layerand the hydroczrbon liquid above it. The relatively thigh outer layerabsorbs the hydrocarbon liquid and increases the carbureting effect.

The air distributor is provided with a float 30 whereby its deliveringmembers main taincd in a substmitially horizontal position at apredetermined depth below the surface of the body of liquid 13. The saidtloat, which may be made of cork or of other suitable buoyantconstruction, is preferably located mainly above the air distributor,and here shovu, is formed to cover the entire area of the airdistributer and project beyond its ends, the float being secured to theair distributer by any suitable means,v such as cars 31 projectin fromthe central member 26, and attachedito the side edges of the float, andU-shapcd straps or loops '32 the ends of which are attached to the underside of the float, said loops embracing the outer end ortions of thetubes 27. The portion of the oat which is immediately over the airdistributor ,is apertured to permit the up ward passage of gas throughthe float, a plurality of apertures 33 being preferably I rol vided forthis purpose. The air whic is discharged into the hydrocarbon liquid bythe distributer passes through the .portion'i of'the liquid locatedabove the distributor and emerges from the a ertnre's*33 as a gas-l Inpractice, where a llirge volume of gas is passing, the rising currentsof gas so agi tate the hydrocarbon liquid as to carry portions of it uwardly tions into bu bleson the upper surface of the float. To enable amass of bubbles to accumulate on the upper surface of the float, I-provide the latter with a curb ill suri roundin the apertured )ortionof the float, said our confining the base of an accumul lation ofbubbles so that they form a sort of niound 35, as indicated by wavybroken lines in Fig. 2. The gas in passing through the mound of bubblesruptures the walls of the bubbles, and thus converts the liquid of whichthey are formed into spray which ,adds to the enrichment of the gas. Then per surface of the float constitutes a bubblie-supporting bed locatedabove the entire series of air outlets, so that the bubbles aresupported in the paths of the ascending jets of air. When a relativelysmall volume of gas is passin the'formation of bubbles does not occur, te bubbles forming and add ing to the enrichment of the gas only when thevolume of gas isv relatively large, so that there is an automaticincrease 1n theuantity of hydrocarbon liquid presented to t e ascendinggas when thevoume of the gas increases.

An important feature of my invention is a substantially horizontal 'airdistributor havin numerous relatively small air outlets o? practicallyuniform size, such as are provided by .the openings in the tubes 27,said outlets constituting the only means for I discharging air into thesurrounding body of hydrocarbon liquid, and being located at differentheights, and therefore at difierent l distances from the-surface of thebody of hydrocarbon liquid, and all being main-, taincd below the saidsurface, so that air issuingfrom each outlet asses upwardly throughliquidabove it. hemrrangement I of the air-distributing outlets atdillerent and form these porl heights is due to the fact that theoutlets are formed in the wall of a tubular air-conducting member,- suchas the tube 27, said member being maintained with its major axissubstantially horizontal, and with its upper i objection is avoided, theincrease ume simply increasing the number of an,

in Fig. 3. As the air volume increases, the displacement of liquid fromthe interior of the tubes 27 is correspondingly increased, and a greaternumber of outlt orifices in the tube become operative to deliver airinto the main body of liquid, as indicated in Fig. i. It will be seen,therefore, that an increase of air volume, instead of forcing the air atgreater velocity through an unvarying number of outlets and through thehydrocarbon liquid, increases the number of jets of air dischar ed,without materially increasing the veocity of its through the liquid,each jet of air being there ore uniformly carburcted. If the air passageoutlets in the distributing members were all I practically at the sameheight or level, or if the distributing members were vertically insteadof horizontally elongated, an increase of air volume would cause the air,to ass with increased velocity through the hy r0- carbon liquid, andthus fail to take up the desired proportion of hydrocarbon va or, theresult being an impoverished as. ith my arrangement of tubulardlstributing members horizontally air outlets located at difierent heithe outlets without materially h increasing velocity of the air passingthroug liquid, so that all the air is uniformly enriched and the maximumefliciency of the apparatus is insured.

Owing to the fact that the air can be discharged into the hydrocarbonliquid only through a multiplicity of small outlets of practicallyuniform size, such as are provided by the perforations of a horizontallyelongated sheet metal tube 27, or by the meshes of a horizontal tube thedischar ed air is wholly in the form of small jets o practically uniformsize, so that all the air is uniformly charged or enriched, no dischar eoii air in relatively large streams or odies which are too large to beuniformly enriched, being possible.

elongated and having hts, this air volof. woven wire,

The

horizontal elongation of the tubes 28 always insures a s'uliicicntnumber outlets topermit the free discharge of air at the pressureexisting in the air supplying conduit. In other words, the airis' not additionally compressed in the tubes 28 and therefore is not dischargedintothe hydroof operative airthe tank, the above mentioned parts may bereadily removedfroni the tank through said opening for repairs, and maysubsequently be reinserted through the same opening, Owing to thehorizontal elongution'oi the distributer and. float, their crosssectional area is relatively small, and. a correspondingly small openingor hand. hole 18 which may be conveniently provided in on end Wall ofthe tank above the liquid level, is sufficient to permit the insertionand re movul of the distributor and float in n horizontal direction. Anadequateopening in an end well may be made of a much smaller size thanone made inthe top, and may therefore be more easily closed'to preventthe escape of gas. v

The hydrocarbon liquid may be introduced through a suitable opening (notshown) in the top of the tank, said opening having a suitable closure.
